Meditations X.12

What need of surmise when it lies with thee to decide what should be done, and if thou canst see thy course, to take it with a good grace and not turn aside; but if thou canst not see it, to hold back and take counsel of the best counsellors and if any other obstacles arise therein, to go forward as thy present means shall allow with careful deliberation holding to what is clearly just? For to succeed in this is the best thing of all, since in fact to fail in this would be the only failure.

Leisurely without being lethargic and cheerful as well as composed shall he be who follows Reason in everything.
